A memory-based storage uses memory as storage device to provide high speed processing of data. Despite its advantage, memory device suffers from several drawbacks such as data maintenance and limited capacity. In this paper, we propose a backup and recovery method of memory-based storage to guarantee fault tolerance. This approach adopts deduplication in which eliminate redundant data for reducing data size. Also, we use a device driver for backup and recovery process that connects memory and backup storage device. The results showed that the proposed method achieves read speed rate of 101% and write speed rate of 71% compared to 'tmpfs' that is memory-based file system of Linux. In addition, we confirmed that it can extend space for backup data without performance deterioration because some of deduplicated data is kept in memory.
